Unita CARD INDEX,

Application led October 2, 1923.

To all whom it may concer/1t.'

Be it known that I, ROBERT C. RUSSELL, a citizen of the United States, Aand resident of Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Card Indexes; and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skill-ed in the art to which it appertains to make and use the same.

This invention relates to improvements in card indexes of the visible type and more particularly to means which will operate to protect the free edge portion of the cards,- one object of my present invention being to provide a simple and effective shield construction which may be easily and quickly applied to the lower free edge portion of a card to protect the same and prevent such soiling of the card as might otherwise occur due to repeated handling.

Viththis and other objects in view, the invention consists in certain novel features as hereinafter set forth and pointed out in the claims.

In the accompanying drawings;

Figure 1 is a front perspective view showing the application of my improvements;

Figure 2 is a rear perspective view, and

Figure 3 is a vertical sectional view.

ln the drawings, I have shown an index card l having hinge connection at 2 with a support 8, portions 4 of the latter projecting beyond the side edges of the card and being adapted to enter guideways in a suitable holder, not shown.

My improved shield or protector 5 is made' of flexible and preferably transparent material, such as celluloid and is bent to form approximately parallel members 6, 7,-the former having somewhat greater width than the other. rlhe free edge portion of the member 6 of the shield or protector is notched to provide a plurality of short elon j gated tongues 8 which are made to project laterally from said member at right angles thereto, so that they may pass through elongated slots or openings 9 in the card l above the lower edge of the latter. The tongues 8 may all be in the same horizontal plane as may1L also be the slots or openings in the car The shield or protector is so formed that Serial No. 668,097.

it shall be resilient and closely embrace the lower edge portion of the card,-the resilience of the member 6 of the device being such that when applied to a card, the locking tongues 8 will snap into the slots 9 in card. Vlfhe shield may be quickly applied to the card and if the locking` tongues be not in proper alinement with the slots or openings 9 in the card, the shield may be moved slightly to eect such alinement, when said tongues will snap into locked relation to the card.

l/Vhen the shield shall have been applied to the card it will be locked against accidental displacement in any direction and it will edectually protect that portion of the card which is grasped by the searcher. Should the card be provided with a label or inscription near its lower edge, the transparent shield will provide an efficient covering for the same.

Having fully described my invention what l claim as new and desire to secure by Letters Patent, is

1. A shield or protector for an edge portion of an index card, consisting of resilient A material and comprising two resilient approximately parallel members, one wider than the other and a lateral elongated tongue projecting from the upper portion of the wider resilient member and in the direction of the plane of the other member and spaced from the latter.

2. A shield or protector for an index card, consisting of resilient material and comprising two approximately parallel members, one wider than the other, the wider member of the shield or protector having at its upper portion a plurality of lateral tongues projecting in the direction of the plane of the shorter member and disposed above the upper edge of the latter.

3. A shield or protector for an index card consisting of resilient material and comprising two approximately parallel members, one wider than the other, the upper edge portion of the wider member being notched and formed with a plurality of elongated tongues projecting laterally in the direction of the plane of the narrower member and spaced above the upper edge of the latter.

4. The combination with an index card having a pulrality of openings above its lower edge, of a resilient shield or protector comprising parallel members to receive the In testimony whereof, I have signed this card between them, one of said members specification in the presence of two subscribbeing Wider than the other, seid Wider meming Witnesses. l
